Comparison of ozone profiles measured by the Odin satellite instruments and ground-based, airborne, satellite experiments and model computations
Bibliographic record
Abstract
The Odin satellite carries two instruments measuring ozone spectra from which strato- spheric ozone profiles are retrieved. Onboard Odin, the Sub-Millimeter Radiometer (SMR) measures an ozone spectral line at 501.4 GHz. Forward model and inversion codes using the Optimal Estimation Method permit the retrieval of vertical profiles in the altitude range 20-65 km. The UV-visible spectrograph of the OSIRIS instru- ment measures ozone absorption limb spectra in the ranges 300-340 and 400-700 nm. A code based on the technique described by Flittner et al. (2000) and McPeters et al. (2000) provides vertical profiles from 20 to 60 km. This work presents a comparison of Odin ozone profiles with those obtained by ground-based measurements from primary or complementary stations of the Network for the Detection of Stratospheric Change (NDSC) such as lidars, microwave radiometers and ozonesondes. Some additional comparisons are also performed with ozone profiles obtained by balloon flights, air- craft experiments, other satellite measurements and model computations. These largesets of comparisons is also used to confirm the soundness of the Odin ozone measure- ments.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
